December 2001 Spindle 6 – 211
MP3412.3 Multiplier for MP3411.x for rigid tapping
Input: 0 to 1.999
MP3415.3 Overshoot behavior of the first spindle during rigid tapping
Input: 0 to 1000 [ms]
MP7130 Run-in behavior of the spindle during rigid tapping
Input: 0.001 to 10 [°/min]
MP7150 Positioning window of the tool axis during rigid tapping
Input: 0.0001 to 2 [mm]
MP7160 Spindle response during Cycle 17 and 18
Format: %xxxx
Input: Bit
0 – Oriented spindle stop with Cycle 17
0: Spindle orientation before execution of Cycle 17
1: No spindle orientation before execution of Cycle 17
Bit 1 – Spindle speed
0: Spindle speed is not limited
1: Spindle speed is limited so that it runs with constant speed
approx. 1/3 of the time
Bit 2 – Spindle in position feedback control
0: Spindle operated without position feedback control
1: Spindle operated with position feedback control
Bit 3 – IPC and acceleration feedforward control
0: Active
1: Not active
Cycle 18 With Cycle 18 the tool axis tracks the actual position of the spindle. The
starting position is the actual position. The target position is the hole depth:
7 7 7 7 Program the approach and departure separately.
M4031 is set while Cycle 18 is running. M4012 must be reset for the cycle to
be executed.
MP3412.3, MP3415.3, MP7130, MP7150 and MP7160 bit 1, bit 2 and bit 3
function as for Cycle 17.
Set Reset
M4030 Cycle 2 or Cycle 17 active NC NC
